I have no idea... A man has three daughters. His friends want to know how many years old the daughters are. The man gives them a hint. HINT #1 The product of their ages is 72. The friends say this is not enough information so the man gives them a second hint. HINT #2 The sum of their ages is equal to my house number. The friends go out and look at his house number and tell the man that they still do not have enough information to determine the ages. The man admits that they need more clue and gives them a third hint. HINT #3 The oldest of the girls likes strawbarry ice-cream. How old are the three girls??
